RELATED APPLICATION(S)

The present application claims the benefit of and priority to a U.S. Provisional Patent Application Ser. No. 62/327,951, filed Apr. 26, 2016, which is hereby incorporated by reference in its entirety into the present application.

BACKGROUND

Conventional action recognition in videos relies on manual annotations of the video frames and/or trained motion tracking, and may be combined with object recognition methods. The dramatic increase in video content, such as amateur videos posted on the Internet, has led to a large number of videos that are not annotated for activity recognition, and may include footage and perspective shifts that make conventional action recognition programs ineffective. Additionally, scene changes, commercial interruptions, and other shifts the video content may make identification of activities in a video difficult using conventional methods.

SUMMARY

The present disclosure is directed to systems and methods for determining actions depicted in media contents based on attention weights of media content frames, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.

DETAILED DESCRIPTION

The following description contains specific information pertaining to implementations in the present disclosure. The drawings in the present application and their accompanying detailed description are directed to merely exemplary implementations. Unless noted otherwise, like or corresponding elements among the figures may be indicated by like or corresponding reference numerals. Moreover, the drawings and illustrations in the present application are generally not to scale, and are not intended to correspond to actual relative dimensions.

FIG. 1 shows a diagram of an exemplary system for determining actions depicted in media contents based on attention weights of media content frames, according to one implementation of the present disclosure. System 100 includes media content 101, computing device 110, and display 191. Media content 101 may be a visual media content, an audio media content, a media content including both audio and video, etc. In one implementation, media content 101 may be a media content including a video content having a plurality of segments made up of a plurality of frames, such as a television show, a movie, etc. In one implementation, media content 101 may include audio content having a plurality of segments including a plurality of audio frames.

Computing device 110 includes processor 120 and memory 130. Processor 120 is a hardware processor, such as a central processing unit (CPU), used in computing device 110. Memory 130 is a non-transitory storage device for storing computer code for execution by processor 120, and also for storing various data and parameters. Memory 130 includes label database 135 and executable code 140. Label database 135 may be a database storing a plurality of labels, segment data used to identify each of the plurality of labels, frame data used to identify the plurality of labels, etc. Label database 135 may include a plurality of action labels and data used to identify a plurality of actions corresponding to each of the plurality of action labels. In some implementations, segment data may be temporal data, such as data related to movement of an object through a plurality of frames, and frame data may be spatial data, such as data describing one or more objects related to labels stored in label database 135.

Executable code 140 includes one or more software modules for execution by processor 120 of user device 110. In some implementations, executable code 140 may attend to parts of media content 101. Executable code 140 may use attention alignment to discern parts of media content 101 that are more important and informative for recognition of an activity in media content 101. In some implementations, activity recognition may be defined as sequential problem where inputs are video features, v_(t), over time. Based on the video feature inputs, executable code 140 may predict a label,

v₁, v₂ . . . , v_(t)

→y, from label database 135. Executable code 140 may be configured as an encoder-decoder framework, where input video features of media content 101 are encoded using Convolutional Neural Network (CNN) models and label prediction is done using Long Short-Term Memory (LSTM) as a decoder. In some implementations, executable code 140 may use Very Deep Convolutional Networks for Large-Scale Visual Recognition from the University of Oxford's Visual Geometry Group (VGG). As shown in FIG. 1, executable code 140 includes segment data module 141, frame data module 143, alignment and attention module 145, and attention module 147.

Segment data module 141 is a software module stored in memory 130 for execution by processor 120 to extract segment data from a video segment of media content 101. In some implementations, video segments may be fixed-length video segments having a fixed number of frames in each segment. Segment data module 141 may extract a plurality of video features using a spatio-temporal Convolutional Neural Network (CNN).

Frame data module 143 is a software module stored in memory 130 for execution by processor 120 to extract frame data from each frame in a video segment of media content 101. Frame data module 143 may extract frame data from each frame of the segment of media content 101 using a spatial CNN. In some implementations, frame data module 143 may be trained to extract frame data for object recognition, action recognition, scene recognition, etc.

Alignment and attention module 145 is a software module stored in memory 130 for execution by processor 120 to align actions depicted in media content 101 with frame data extracted by frame data module 143 and determine an attention weight for each frame in the segment of media content 101. Alignment and attention module 145 may be a feedforward neural network that may generate a matching score for each frame from which frame data module 143 extracted frame data at a defined time interval t. The matching score may represent how well a sequentially modeled activity video up to time t−1 and the frame at time t are semantically matched. In some implementations, alignment and attention module 145 may determine the attention weight for each frame of the segment of media content 101 based on the matching score. Alignment and attention module 145 may compute attention weights for the frames of the segment by normalizing the matching scores using a normalized exponential function, such as a softmax function.

FIG. 6 shows a flowchart illustrating an exemplary method of determining actions depicted in media contents based on attention weights of media content frames, according to one implementation of the present disclosure. In some implementations, executable code 140 may be trained with stochastic gradient descent with momentum of 0.9 and learning rate of 0.01. Training may apply dropout with probability 0.5 to all LSTM non-recurrent connections and fully-connected layers. Training may use a fixed 0.01 learning rate for 2512 iterations on mini-batches of size 200. After that, the learning rate may be decreased every 125 iterations by a fixed ratio. Training may use an early stopping strategy on validation set loss. The dataset may be augmented by adding horizontally-flipped frames to training data. In some implementations, training executable code 140 may include an on-the-fly temporal cropping of training videos, which means that at each iteration, a fixed-size video chunk of 192 frames may be randomly cropped from each video sample in the mini-batch.

Method 600 begins at 610, where executable code 140 receives media content 101 including a plurality of segments, each segment of the plurality of segments including a plurality of frames. Media content 101 may be a television show, a television broadcast, a movie, etc. Method 600 continues at 620, where executable code 140 extracts a first plurality of features from a first or a given segment of the plurality of segments. In some implementations, each segment of media content 101 may be a fixed temporal-length segment of F frames. Segment data module 141 may extract video features from this segment using spatio-temporal CNN implemented in Caffe. As a result, the input segment may be represented using a matrix V={v ₁ , . . . ,v _(N) }∈R ^(N×d) ^(v)   (1) of N video feature vectors, where each vector v_(i)∈R^(d) ^(v) is a d_(v)-dimensional representation corresponding to a chunk of F/N frames. In some implementations, N may also correspond to the length of the LSTM decoder sequence, such that for every video feature vector, executable code 140 may provide an activity label prediction. For example, executable code 140 may make use of a C3D network pre-trained on Sport-1-million dataset that has been fine-tuned on trimmed ActivityNet videos. C3D network has eight (8) convolutional layers and two (2) fully connected layers, followed by a softmax output layer. All three-dimensional (3D) convolution kernels are 3×3×3 with stride one (1) in both spatial and temporal dimensions. Segment data module 141 may extract a first Fully-Connected layer (FC6) as a feature vector representation, therefore d_(v)=4096.

At 630, executable code 140 extracts a second plurality of features from each frame of the plurality of frames of the first segment. Frame data module 143 may extract frame data using spatial CNN in Caffe. As a result, frame data may be represented using a matrix: A={a ₁ , . . . ,a _(T) },a _(i) ∈R ^(T×d) ^(a)   (2) of T video feature vectors where each vector a_(i)∈R^(d) ^(v) is a d_(a)-dimensional representation corresponding to a single frame. In some implementations, each segment is sampled every F/N video frames, therefore T=N. Frame data module 143 may use a VGG-19 network trained for three tasks of object, action, and scene recognition:

-   -   1. VGG_(obj): VGG trained on ImageNet for object recognition of         1000 classes;     -   2. VGG_(act): VGG-19 network fine-tuned on ActivityNet data for         action recognition of 203 action classes; and     -   3. VGG_(sce): VGG-19 network fine-tuned on MIT-Scenes for scene         recognition of 205 scene classes.         VGG-19 may have sixteen (16) convolutional layers and three (3)         fully connected layers, followed by a softmax output layer. In         some implementations, frame data module 143 may extract a first         Fully-Connected layer (FC6), therefore d_(a)=4096. In other         implementations, frame data module 143 may extract a last         Fully-Connected layer (FC8) as a frame representation. For         VGG_(obj) FC8 layer d_(a)=1000, for VGG_(act) FC8 layer         d_(a)=203, and for VGG_(sce) FC8 layer d_(a)=205. In general,         the size of T could be different from the size of input-data         N(T≠N). For example, executable code 140 may attend to         objects/scenes/actions at a coarser or finer temporal         granularity compared to the granularity of label predictions.

At 640, executable code 140 generates a matching score for each frame of the plurality of frames of the first segment based on each preceding frame in the first segment. Alignment and attention module 145 may be parameterized as a feedforward neural network and may be jointly trained with LSTM decoder, such that the gradients of LSTM loss function are back propagated not only through LSTM network, but also through alignment network that allows joint training of LSTM and soft-alignment networks. Alignment and attention module 145 may determine a score for each attended frame a_(i) at time step t. This score represents how well a sequentially modeled activity video up to time t−1 and attended a_(i) are semantically matched. In other words, matching score m_(t,i) reveals the relevance of a_(i) and LSTM decoder hidden state at time t−1 and is defined as m _(t,i)=Φ(h _(t-1) ,a _(i))  (3) where h_(t-1) is an LSTM decoder hidden state at time t−1 that contains all information related to a temporally modeled video sample up to time step t−1. For alignment model Φ, every state h_(t-1) may be summed with every frame data a_(i) to obtain matching-vectors. Each matching-vector may be transformed into a single number, matching-score m_(t,i). In some implementations, the alignment model matching-vector dimension may be one of the network parameters and may have different value than the LSTM hidden-state.

At 650, executable code 140 determines an attention weight for each frame of the plurality of frames of the first segment based on the first plurality of features extracted from the first segment and the second plurality of features extracted from each frame of the plurality of frames of the first segment. In some implementations, alignment and attention module 145 may compute attention weights for each frame of the segment by normalizing matching-scores in a softmax-like function. Attention weight w_(t,i) for attended frame i at time t may be computed by:

$\begin{matrix} {w_{t,i} = \frac{\exp\left( m_{t,i} \right)}{\sum\limits_{j = 1}^{T}{\exp\left( m_{t,j} \right)}}} & (4) \end{matrix}$ Soft-alignment between a label and the attended frames are defined based on attention weights. A higher attention weight reflects more saliency attributed to a specific attended frame i with respect to the specific action classification. In order to integrate frame data with LSTM decoder, alignment and attention module 145 may compute a weighted average of the frame data, referred to as action attention context, using the attention weights determined above.

$\begin{matrix} {{k_{t}(A)} = {\sum\limits_{i = 1}^{T}{w_{t,i}a_{i}}}} & (5) \end{matrix}$

At 660, executable code 140 determines that the first segment depicts content including one of the plurality of labels in label database 135 based on the first plurality of features, the second plurality of features, and the attention weight of each frame of the plurality of frames of the first segment. In some implementations, aLSTM decoder ψ may sequentially update LSTM state h_(t) and internal memory c_(t) given previous state h_(t-1), current input-data v_(t), and action attention context vector k_(t)(A). aLSTM decoder ψ may also predict label y_(t) at time t. aLSTM decoder ψ may be defined as:

$\begin{matrix} {\begin{bmatrix} h_{t} \\ y_{t} \\ c_{t} \end{bmatrix} = {\psi\left( {h_{t - 1},v_{t},{k_{t}(A)}} \right)}} & (6) \end{matrix}$ In order to fuse input-data and frame data, the information from action attention context may be distributed across the input-data v_(t). In some implementations, h_(t) may be updated by the following intermediate functions: i _(t)=σ(W _(i) v _(t) +U _(i) h _(t-1) +b _(i))  (7) f _(t)=σ(W _(f) v _(t) +U _(f) h _(t-1) +b _(f))  (8) o _(t)=σ(W _(o) v _(t) +U _(o) h _(t-1) +b _(o))  (9) g _(t)=tan h(W _(c) v _(t) +U _(c) h _(t-1) +b _(c))  (10) c _(t) =f _(t) c _(t-1) +i _(t) g _(t)  (11) h _(t) =o _(t) tan h(c _(t))  (12) where i_(t), f_(t), o_(t), and c_(t) are respectively input gate, forget gate, output gate, and cell gate (i.e., internal memory) at time t. In brief i_(t), f_(t), and o_(t) control the influence of current input g_(t) and previous memory state c_(t-1) on generating new hidden state h_(t). The prediction y_(t) may be computed by linear transform on hidden state h_(t) followed by a softmax: y _(t)=softmax(W _(y) h _(t) +b _(y))  (13) where y_(i)∈R^(C) is probability distribution over fixed number of C classes.

At 670, executable code 140 tags first segment of the plurality of segments with an activity label based on the determined label of a first or a given frame. In some implementations, the activity label may be inserted into media content 101 as metadata, using a metadata container, etc. Method 600 continues at 680, where executable code 140 transmits the first segment to display 191 for display. In some implementations, executable code 140 may transmit the first segment over a network, such as a local network or over the Internet.

At 690, executable code 140 performs an act based on a user input and the label. In some implementations, executable code 140 may begin playing skip a segment of media content 101 based on the user input if the plurality of frames in the segment have or do not have a particular tag. For example, if a user is watching a previously recorded tennis match, the user may provide an input to skip over a segment included that does not show players playing tennis, such as commentary between matches and/or a break to show advertisements. Frames depicting the tennis match may include a tennis tag, whereas the commentary and the advertisements do not. When the user reaches the end of one tennis match, the user may provide an input to forward playback of media content 101 to the next tennis match, and executable code 140 may skip one or more segments of media content 101 that do not include the tennis tag. In other implementations, a user may provide an input to record segments of media content 101 that include a particular tag. For example, the user may want to record a golf tournament to watch at a later time. The user may provide an input instructing executable code 140 to record segments tagged golf. In response to the user input, executable code 140 may record portions of a golf broadcast the show players playing golf, and not record segments of commentary, advertisements, etc.

A method for use with a system including a non-transitory memory and a hardware processor, the method comprising: receiving, using the hardware processor, a media content including a plurality of segments, each segment of the plurality of segments including a plurality of frames; extracting, using the hardware processor, segment data from a segment of the plurality of segments; extracting, using the hardware processor, frame data from each frame of the plurality of frames of the segment; determining, using the hardware processor, an object attention weight, a scene attention weight, and an action attention weight for each frame of the plurality of frames of the segment based on the segment data extracted from the segment and the frame data extracted from each frame of the plurality of frames of the segment; determining, using the hardware processor, that the segment depicts a label of the plurality of labels in the label database based on the segment data, the frame data, the object attention weight, a scene attention weight, and an action attention weight of each frame of the plurality of frames of the segment; tagging, using the hardware processor, the segment with the label; receiving, using the hardware processor, a user input from a user device; and performing, using the hardware processor, an act on the media content based on the user input and the label.
 12. The method of claim 11, wherein, prior to determining the object attention weight, the scene attention weight, and the action attention weight for each frame of the plurality of frames of the segment, the method further comprises: generating, using the hardware processor, a matching score for each frame of the plurality of frames of the segment based on each preceding frame in the segment.
 13. The method of claim 11, wherein the frame data extracted from each frame of the plurality of frames of the segment includes at least scene data, object data, and activity data.
 14. The method of claim 11, wherein the object attention weight, the scene attention weight, and the action attention weight for each frame of the plurality of frames of the segment is based on at least one of a complementary scene data source, a complementary object data source, and a complementary activity data source.
 15. The method of claim 11, wherein the segment data includes temporal data and the frame data includes spatial data.
 16. The method of claim 11, wherein each frame of the plurality of frames in the segment is considered in determining that the label of the plurality of labels in the label database is included in the frame in proportion to the object attention weight, the scene attention weight, and the action attention weight.
 17. The method of claim 11, wherein the object attention weight, the scene attention weight, and the action attention weight of a frame of the plurality of frames of the segment is based on at least one of the object attention weight, the scene attention weight, and the action attention weight of one or more frames preceding the frame in the segment and the object attention weight, the scene attention weight, and the action attention weight of one or more frames succeeding the frame in the segment.
 18. The method of claim 11, further comprising: transmitting, using the hardware processor, the segment to a display device for display.
 19. The method of claim 11, wherein the tagging of the segment with the label includes inserting the label into the media content using a metadata container.
 20. The method of claim 11, wherein the performing of the act based on the user input and the label includes one of skipping the segment and recording the segment.
